TL;DR: A high-quality reference genome assembly for threespine stickleback fish is developed and it is indicated that reuse of globally shared standing genetic variation has an important role in repeated evolution of distinct marine and freshwater sticklebacks, and in the maintenance of divergent ecotypes during early stages of reproductive isolation.

TL;DR: These studies illustrate how major expression and morphological changes can arise from single mutational leaps in natural populations, producing new adaptive alleles via recurrent regulatory alterations in a key developmental control gene.

TL;DR: Emergent trends and gaps in understanding are identified, new approaches to more fully integrate genomics into speciation research are proposed, and an integrative definition of the field of speciation genomics is provided.

TL;DR: Fish from high- and low-predation regions within four streams that run independently into the Panama Canal were tested and boldness scores were strongly influenced by standard length and the relative level of predation pressure in the rivers.
